Definitions
- the means for collecting the liquid as it flows downward off of the roller and removing said liquid from the evaporator chamber includes a worm auger disposed coaxially below said roller and adjacent thereto, said worm auger having an inlet for collecting said liquid flowing down from said roller, and an outlet which communicates with an exit duct provided in said chamber, and said roller rotating means being provided for rotating said worm auger thereby causing it to transfer the liquid collected from the roller out of the evaporator chamber through said exit duct.
